Most people like to travel and go on vacation. I know I do, although I rarely get to do so because it’s also expensive. There are 1 billion tourist that visit other countries in the world every year. In this age of mass tourism, when more of us than ever are leaving home for more exciting climates.

Unfortunately, tourism often puts pressure on natural resources through over-consumption, often in places where resources are already scarce.

There are many things that put pressure on coral reefs. For example, 80% of the coral around the Maya bay has been destroyed, the result of millions of boats dropping anchor on it, tourists treading on and picking it, or poisoning by rubbish and sun-cream.
